To all whom it may concern: 16, having a threaded extension or screw 17,Beit known that l, SOLOMON MURPHY, a extending across the nut -retainer13 and citizen of the United States, residing at Northrough the slottherein. Engaging the Screw folk, in the county of Madison and State ofis a nut 1S, grooved at 19 to permit it to enter 5 5 5 Nebraska, haveinvented a new and useful the retainer-slot and having at its outer endRule Attachment, of which the following' is a thumb portion 20. aspecification. Between the bottom of the guide portion My inventionrelates togages, and more of the frame and the end of the bracket 14 isparticularly to an adjustable head adapted a stud or rivet 21, uponwhich is rotatably 6o 1o for use upon rules and the like,journaledacontact member or roll 22 of suflilt has for its objects theprovision of a comcient diameter to project beyond the frame pact andaccurate device of this class which at the end opposite the curvedbracket and shall be applicable to shafts or members of thus furnish aworking face.
